Renesas ISL97634IRT14Z-TK

DC DC 稳压器2.4V5.5V70mA

Overview

The ISL97634IRT14Z-TK represents an efficient and highly integrated PWM boost LED driver that is suitable for LED backlighting in small size LCD panels. With integrated Schottky diode, OVP, and wide range of PWM dimming capability, the ISL97634IRT14Z-TK provides a simple, reliable, and flexible solution to the backlight designers.The ISL97634IRT14Z-TK features a wide range of PWM dimming control capability. It allows dimming frequency as low as DC to 32kHz beyond audible spectrum. The ISL97634IRT14Z-TK also features a feedback disconnect switch to prevent the output from being modulated by the PWM dimming signal that minimizes system disturbance.The ISL97634IRT14Z-TK is available in the 8 Ld TDFN (2mmx3mm) package. There are 14V, 18V, and 26V OVP options that are suitable for various number of LEDs in series. The ISL97634IRT14Z-TK is specified for operation over the -40°C to +85°C ambient temperature at input voltage from 2.4V to 5.5V.
